With reference to FIG. 2A, in an automatic alignment and label attaching apparatus 1000 according to an embodiment of the present invention, the basket 1100 and the test tube supply device 1200 are configured in one set to be coupled to a frame of the automatic alignment and label attaching apparatus 1000 in a tray form. FIG. 2A illustrates the basket 1100 and the test tube supply device 1200 slidably coupled in a tray form as an example, but the present invention is not limited thereto and may have any form that may be easily coupled as one set formed in a module.

With reference to FIGS. 2B to 2C, the automatic alignment and label attaching apparatus 1000 according to an embodiment of the present invention may include a basket 1100 and a test tube supply device 1200.

The basket 1100 according to an embodiment of the present invention may be formed in a box shape, and an upper surface thereof may be opened and a bottom surface thereof may be concave. The bottom surface of the basket 1100 may be formed in a semicircular shape or a fan shape corresponding to a radius of rotation of a swing bar 1210 to be described later based on a cross section taken along line A-A. That is, the bottom surface of the basket 1100 may be formed concave with a radius of curvature of a length corresponding to the radius of rotation of the swing bar 1210. More specifically, the radius of curvature of the bottom surface of the basket 1100 may be formed slightly longer than the radius of rotation of the swing bar 1210 and may be formed not to interfere a rotation of the swing bar 1210.

The basket 1100 according to an embodiment of the present invention may supply the test tube 2000 to the automatic alignment and label attaching apparatus 1000 through an open portion in a box form having an opened upper surface. When the test tube 2000 is supplied to the basket 1100, it is unnecessary to separately supply the test tube in a pallet in an alignment manner, and the test tubes may be supplied in a randomly pouring manner. The test tubes 2000 supplied to the basket 1100 are collected at the center of the basket 1100 along a concave shape of the bottom surface of the basket 1100.

The test tube supply device 1200 according to an embodiment of the present invention may include a swing bar 1210, a first buffer 1220, and a second buffer 1230.

The swing bar 1210 according to an embodiment of the present invention may rotate in a form of sweeping a bottom surface of the basket 1100 with a rotation shaft at a wall of a width direction of the basket 1100. The swing bar 1210 may include a first rod 1211 connected to the rotating shaft to provide a radius of rotation of the swing bar 1210 and a second rod 1213 formed to elongate in a width direction of the basket 1100 to sweep the bottom surface of the basket 1100.

The rotation shaft of the swing bar 1210 according to an embodiment of the present invention may be formed at both opposite side walls or at only one side wall. The swing bar 1210 may reciprocate in a range in which the swing bar 1210 does not protrude to the outside of the basket 1100 rather than rotating without a limit when rotating about the rotation shaft.

The second rod 1213 of the swing bar 1210 according to an embodiment of the present invention may align the test tubes 2000 randomly supplied to the basket 1100 while rotating to sweep the bottom surface of the basket 1100.

The first seating groove 1221 may elongate in a width direction of the basket 1100 and may be formed so that the test tubes 2000 are seated only in one row in the width direction. However, two or more test tubes 2000 may be seated in a width direction in a range formed in one row.

The inclined wall 1223 according to an embodiment of the present invention may be rotatably disposed at a widthwise wall of the basket 1100 and may be inclined toward the first seating groove 1221. As the inclined wall 1223 rotates, the first buffer 1220 may be opened and the test tube 2000 may be transferred to the second buffer 1230. Further, as the inclined wall 1223 is formed to be inclined toward the first seating groove 1221, another test tube may be prevented from being stacked on the test tube 2000 seated in the first seating groove 1221. In a cross-section taken along line A-A of FIG. 2B, an inclination level of the inclined wall 1223 along the first seating groove 1221 should be formed so that the test tubes 2000 in which the center of the test tube 2000 seated the first seating groove 1221 and the center of the test tube stacked thereon are stacked with twistedly aligned instead of being vertically aligned fall again to the bottom surface of the basket 1100.

The second buffer 1230 according to an embodiment of the present invention may be positioned at the lower side than the first buffer 1220 while being positioned in parallel to the first buffer 1220 in one side direction of the basket 1100. The second buffer 1230 may include a second seating groove 1231, a conveyor 1233, and a release device 1235.

The second seating groove 1231 according to an embodiment of the present invention has a shape to enable the test tube 2000 transferred from the first buffer 1220 to be stably seated and may elongate in a width direction of the basket 1100, as in the first seating groove 1221. The second seating groove 1231 may have a width to enable the test tube 2000 to be seated in one row, as in the first seating groove 1221 and have a length to enable two or more test tubes 2000 to be seated.

The conveyor 1233 according to an embodiment of the present invention may be formed at the bottom surface of the second buffer 1230 to enable the test tube 2000 to move to an end portion of one side in the second seating groove 1231. For example, as illustrated in FIG. 2B, the conveyor 1233 may feed the test tube 2000 to the end of a left end direction in the second seating groove 1231. The conveyor 1233 may be formed in various forms such as a belt type and a roller type, and may have a form that may feed the test tube 2000 in the second seating groove 1231.

The releasing device 1235 according to an embodiment of the present invention may separate the test tube 2000 fed from the inside of the second seating groove 1231 to an end portion of one side from the second buffer 1230 and transfer the test tube 2000 to the test tube feeder 1300.
